What is Blockchain? For beginners in 2023

In recent years blockchain or blockchain technology has been heard while investing in cryptocurrency, as many people are unaware of their terms and usage. Hence this article will give you an understanding of Blockchain and how it works with cryptocurrency.


What is Blockchain?

Blockchain is a system of recording information, making the change or cheating the system extremely difficult. This chaining technology means that every step you choose should be related to the dependent on the previous one.

The digital ledger of the transaction is duplicated across the entire network of a computer system on the it, as it keeps every transaction.

Every block contains  several chains of transactions, and there is a new transaction on it every time. It has the record of the transaction added to every participant at the same time, so cheating does not happen.

The decentralized database is managed by multiple participants, known as Distributed Ledger Technology (DLT). It is a DLT type where transactions are recorded with an immutable cryptographic signature called a hash.

In other words, if one block is changed, then it would be immediately apparent tampering in the system. If a hacker wants to hack or corrupt the blockchain database, he should simultaneously change the entire block in the chain.

There are many blockchains, but the oldest and most powerful are bitcoin and Ethereum, which are constantly and continually growing as the global block and added the chain, which signifies security and privacy.

Properties of DLT

There are several properties of DlLT:

  1. Distribution
  2. Immune
  3. Anonymous
  4. Programmable
  5. Unanimous

Distribution: It has the network participants who have a copy of the ledger to make it completely transparent.

Immune: Immune is to validate the record on the it, which cannot be changed or reversed.

Anonymous: The identity of the participants is either anonymous, which is the biggest factor in it.

Programmable: It is programmable, which means it is secure, and the block is secure as the individual’s records of the individual are encrypted.

Unanimous: All the participants agree to the validities of each ground record at a time-bound time, and  as the transaction is time-stamped.

How does the Blockchain Work?

The main goal of the Blockchain is to allow digital information to the recorded and distributed. It’s foundation is immutable, so the transaction records cannot be spread, altered, deleted, or destroyed. That is why it is known to be Distributed ledger technology (DLT).

It has the transaction process and Attributes of Cryptocurrency.

Transaction Process: Whenever the transaction is entered, it goes to the network of worldwide peer-to-peer computers.

Then that network goes to the computer to solve the equation and confirm the transaction’s validity.

And once it is confirmed then, the transaction is clustered together into blocks.

These blocks are then chained together, creating a long history of permanent transactions. And hence the transaction is completed.

Attributes of Cryptocurrency:

It is used to store cryptocurrency transactions and other legal contracts.

It has intrinsic value, a secure and fast way to transfer the value at no cost. And has no physical form that exists on the immutable.

Attributes of the cryptocurrency are supplied and decided by most members of its decentralized network instead of a central bank.

Is Blockchain secure?

Yes this technology is secure and maintains privacy, which is linearly sorted.

Advantages of Blockchains

  1. It has improved accuracy, that is, no human involvement in verification.
  2. It has a cost reduction, which is by eliminating the third party.
  3. Transactions are secure and private.
  4. Transparent Technology.

 A disadvantage of Blockchain.

  1. It is associated with the mining of bitcoin.
  2. Low transaction per second.
  3. It has data storage limitations.
  4. It regulates varies by juridication.


As this technology is being explored, the Blockchain is part of bitcoin and cryptocurrency.

As an investor, it stands to make business and government operations more accurate, efficient, secure, and cheap.

Frequently Asked Question

How many Blockchains are there?

They are growing every day. It is more than 10,000 active cryptocurrencies based on them.

What is the difference between Private  and Public Blockchain?

A public , also known as open or permissionless, is one where anybody can join the network freely.

A private or permissioned blockchain requires each node to be approved before joining.
